At constant temperature, current through a conductor is directly proportional to potential difference across it, giving V = IR.

Electrical power formula

Power in a circuit equals voltage times current, P = VI, and can also be written I²R or V²/R.

Speed of light in vacuum

Light travels in vacuum at approximately 3 × 10⁸ metres per second, the fastest speed possible in nature.

Kinetic energy

The energy possessed by a body due to its motion, calculated as one-half times mass times velocity squared.

Quadratic formula

For ax² + bx + c = 0, the roots are minus b plus or minus the square root of b² − 4ac, all divided by 2a.

Discriminant of a quadratic

The value b² − 4ac; if positive roots are real and distinct, if zero they are equal, if negative they are imaginary.

Sum of an AP

For an arithmetic progression, the sum of n terms is n/2 times twice the first term plus (n − 1) times the common difference.

Pythagorean identity

Aerobic endurance test

A timed run such as 1.6 kilometres measures cardiovascular endurance; a shorter completion time indicates better aerobic fitness.

Sit-and-reach test

A flexibility test in which the farthest forward reach from a seated position is recorded, reflecting hamstring and lower-back flexibility.

Estimated maximum heart rate

A commonly used estimate of maximum heart rate is 220 minus age in years; training zones are set as percentages of this value.

Progressive overload

Gradually increasing training intensity or volume over time so the body adapts, balanced with adequate rest to prevent injury.

Muscular endurance test

Push-ups and sit-ups performed within a fixed time measure muscular endurance, scored by the number of correct repetitions.

Adaptability response steps

In a situational test, identify the problem, choose a practical action, and communicate it clearly to the team.
